The iPad Air 2 is a nice refinement and finesse of last year's model, with a bevy of tweaks, enhancements, a much faster processor, and the welcome addition of Touch ID. Simply put: it's still the gold standard for tablets.

Although the Nexus 6 trails the slimmer Samsung Galaxy Note 4 in processor performance and native productivity features, it's still the most powerful pure Android handset available and the largest Nexus yet.
